THEODORE E. HASLEHURST, OF

MODE OF SECURING CERTAIN PARTS OF SUBTERRANEAN PIPES.

SPECIFICATION forming part of Letters Patent No. 233,183, dated October 12, 1880.

- Application filed May 11, 1880. (No model.)

To all whom it may concern Be it known that I, STEPHEN E. BABCOOK, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in the Mode of Securing Certain Parts of Subterranean Pipes for Steam and other Heated Fluids, of which the following is a specification.

The object of my invention is to remedy certain serious defects that have heretofore existed in maintaining in a fixed position and in an unleaky condition the elbows and other devices used. for changing the course of underground mains for steam and other hot fluids. These defects have mainly proceeded from the longitudinal expansion or" the mains, which, when no expansionjoints are used at their junction with the elbows, 850., causes the joints to break and become leaky, and where expansion-joints are used the elbow or other device soon becomes displaced and thrown out of line with the mains. By reason of the expansion of the mains and the pressure of the steam acting against the unsecured elbow, &c., or by either of these causes, the line of pipes soon becomes leaky and unserviceable.

To remedy these defects, my invention consists in providing each branch of the elbow, T, cross, or other device with a suitable expansion-joint, and then securing said elbow, &c., in a fixed position between abutments of masonry, whereby they will successfully resist the tendency of the forces above named to (lisplace them.

In the accompanying drawings, which form a part of this specification, and to which reference is herein made, Figure l is a horizontal section of an elbow, and Figs. 2 and 3 are respectively plan views of aT-pipe and a crosspipe, all of said devices being shown as secured in place by my improved mode.

As illustrated in the drawings, A represents abutments of masonry, which should be made of suitable form to fit the device with which it is used, and of sufficient strength to resist the strain thrown upon them by the expansion of the mains and by the pressure of steam acting against the elbow or other device to throw it out of place.

In Fig. 1, B is an elbow-pipe, provided at each of its ends with a stuffing-box, b, of ordinary form, which permits the ends of the main pipe 0 to slide freely in the elbow, to compensate for the expansion and contraction of the mains, while the packing in the stuffingbox produces a steam-tight joint between the mains and the elbow. Said elbow-pipe is placed in position between the two abutments A, and when the two ends of the elbow are brought to range in line with the two lines of the mains the keys D are driven between the elbow-pipe and abutments, as shown in Fig. 1, and hold the elbow securely in place.

In Fig. 2, B is a T-pipe, provided at each end with a stuffing-box, b, for receiving the ends of the mains G, as above described. Said T-pipe is placed between the three abutments A, and secured therein, in the manner above specified, by the keys D.

In Fig. 3, B is a cross-pipe, provided with a stuffing-box, b, at each of its ends, for the purpose above set forth. Said cross-pipe is placed between the four abutments A, and secured, as hereinbefore described, by the keys D.

Instead of the ordinary form of slip expansion-joint, (represented by the stuffing-box b and the ends of the mains (J in the drawings,) any other suitable form of expansion-joint may be used for connecting the mains to the elbows, &c.,and the expansion-joints used need not be made a part of the elbow, &c., but may be placed in the mains ashort distance therefrom.

I claim as my invention-- In a subterranean main for steam or other hot fluids, the combination, with an elbow, B, or other device for changing the course of the main or mains, and provided with expansionjoints, as herein described, of the abutments A and keys D, for holding the elbows, &c., in a fixed position, as herein specified.

STEPHEN E. BABOOCK.
